Based on the following code, how can I add a column to this pivot table
output that will count CaseID's for each variable sum?  CaseID is a factor.

# library(reshape)
# FLSA_Violation_Reason_melt <- melt(FLSA_ViolRsnfixed, 
#                                    id=c("CaseID", "ViolationDesc",
#                                    measure=c("BW_Due", "BW_ATP",
# FLSA_Violation_Reason_cast <- cast(FLSA_Violation_Reason_melt, 
#                                    ViolationDesc + ReasonDesc ~ variable,
#                                    sum, margins=TRUE)

Thank you.
